The main function of the stretch film is to pack the goods together and wrap the scattered goods together to prevent the loss of the goods. This kind of stretch film packaging material is suitable for the logistics industry. In addition, the stretched film is moisture-proof and scratch-resistant, and is extremely protective because the tightness of the stretched film can protect the article. Today, the joypack stretch film manufacturer will introduce to you what are the factors that affect the tightness of stretch film.

1. Non-polar polymer, the surface freedom of the stretched film is small, and the tension is low, generally about 30 dyne/cm.

2. Polyester, polyethylene terephthalate, polyethylene terephthalate, PETG are polar polymers with high surface free energy and surface wet tension higher than 40 dyne/cm.

3. The transfer of the aluminized layer will occur when aluminizing, and the transfer of the glue layer will occur when applying glue.

Especially important is the stretch film packaging, so that the packaged goods must be uniformly stressed to avoid damage to the goods due to uneven force, which is not possible with traditional packaging (bundling, tape, etc.).

The stretched film has super winding force and elasticity, which can bind the product tightly and fixedly into a unit, so that the scattered goods are bundled as a whole, even in adverse environments, the goods are not Will separate loosely, without sharp edges and stickiness, to avoid damage.

At the same time, the stretching force of the stretch film can be adjusted, which can make the hard products fit each other and shrink the soft products, especially in the tobacco industry and the textile industry.
